Mir Status 20 October 1997

The second IVA into Spektr was conducted today, and the crew connected two of the three cables for the solar array orientation system to the hermaplate on the hatch. They were unable to make one of the connections due to difficulties with access, so one of the three undamaged arrays will not be steerable. The MOST is attempting to find out which one this is, but it is believed to be the array opposite the damaged array. The current plan is to make the connection to the Kristall avionics on Wednesday, the 22nd.

Mr. Blagov told us that they do not yet know the cause of the failure to depressurize the Progress vestibule on Saturday. They suspect that a limit switch was not making contact, preventing the supply of power to the valve. However, the depressurization worked fine on Sunday. He said that the crew will take a closer look for causes when they reopen Progress.

Mir Payload Activities

SPEKTR IVA
MG:FAC:I:39 BEM/BSTC-M & BTR Facility Maintenance

IVA Powered Hardware Operations

Network Status - A total loss of communication, including telephone, fax, e-mail, and voice loop occurred at 1300 DMT today. Marshall opened two trouble tickets to determine the anomaly. Communication between the TsUP and the US was restored at approximately 20:00 DMT, and the anomaly was determined to be a loss of both circuits due to a faulty memory card on Node 214.

Experiment Hardware

BSTC-M - Dave reported that the temperatures of the first two chambers were 34 and 35 degrees, and the setpoint was still at 36 degrees. He also mentioned that the air inlet temperature is warmer and up to 32.4 degrees since the BSTC is in a warmer spot now (has been around 29).

ISSUES - Due to the IVA running slightly overtime, there will be no telemetry available this evening. This will prohibit the re-powering of the Priroda module and therefore the CAPE/MIM equipment will not be re-powered as planned. This will be the first activity tomorrow post Priroda power-up.

During the 20:59-21:14 Wallops comm pass the link from Mir to ground was not successful. Wallops could hear the crew, but due to problems in Moscow the MCC-M could not hear the crew. During the next pass, comm was nominal.
